The concrete steps of described strip foundation construction are: described strip foundation adopts concrete cast-in-situ, and preformed groove position, to guarantee building by laying bricks or stones smoothly of concrete modular, concrete continuous footing and preformed groove the construction line-putting position are accurate, and it is corresponding with the barricade settlement joint that concrete continuous footing arranges settlement joint.
10. the job practices of Fill Reinforced With Geogrids body of wall according to claim 9 is characterized in that, described surface layer system by concrete bear down on one, railing, rubble drainage blanket, concrete modular, mortar mask, gutter, concrete continuous footing form; The concrete steps of described Fill Reinforced With Geogrids structure construction are: described geo-grid is unidirectional geo-grid, hanging wire is with the mortar laminated concrete modular of building by laying bricks or stones on concrete continuous footing, then begins the connection of unidirectional grid and the roller compaction construction of backfill gravel drainage blanket and filler within the walls; Every laying one deck unidirectional grid, end connecting reinforcement net or a skeleton reinforcing steel bar of exposing at unidirectional grid; The Specific construction process is as follows:
(1) press the unidirectional geo-grid of design length cutting, must satisfy the requirement of geo-grid design length during cutting, the cutting position is the middle position of geo-grid longitudinal rib;
(2) prefabricated concrete modular is built in layering by laying bricks or stones;
(3) lay the unidirectional geo-grid of first floor;
(4) with pitman unidirectional geo-grid and concrete modular being reserved grid is connected or lays with connector hook grid;
(5) with the stretch-draw beam unidirectional geo-grid is strained, free end is passed skeleton or steel mesh reinforcement bending, fix with pitman, then decontrol the stretch-draw beam;
(6) with loader sandy gravel and filler vertically are poured on the basis of completing unidirectional geo-grid, with excavator or the smooth sandy gravel of bulldozer, shake rolling machine with the sandy gravel compacting with halo, form the backfill packing layer, in the inboard near concrete modular the rubble drainage blanket is set successively, gutter is arranged in rubble drainage blanket and the concrete modular;
(7) repeat above operation to the barricade concrete position of bearing down on one, bearing down on one at concrete arranges railing; Faulting of slab ends end face in the setting of surface layer system arranges the mortar mask;
(8) top layer concrete modular is connected with unidirectional geo-grid, and unidirectional geo-grid laying length is consistent with lower floor.
